The present invention provides a laminate film and a display member including the laminate film, which are excellent in visibility of external information such as scenery and displayability of information from a projection member, and are also excellent in color tone reproducibility. The laminate film includes a laminate of 50 or more alternately arranged layers of a plurality of different thermoplastic resins, the laminate film having a transmittance of light incident perpendicularly to a film surface of 50% or more, the laminate film satisfying a relationship of R20&#x2264;R40&#x3c;R70, wherein R20, R40, and R70 are reflectances of a P-wave incident at angles of 20&#xb0;, 40&#xb0;, and 70&#xb0;, respectively, to the normal to the film surface, the reflectance of R70 being 30% or more, reflected light of the P-wave incident at 70&#xb0; to the normal to the film surface having a saturation of 20 or less.

Layered film and display device

The present invention provides a light source unit capable of displaying an image of a desired color without causing color unevenness when mounted on a display. A light source unit including: a light source; a color conversion member that converts incident light incident from the light source into light having a longer wavelength than the incident light does; and a reflective film that is present between the light source and the color conversion member, transmits light incident from the light source, and reflects light exited from the color conversion member, wherein in the reflective film, the scattering angle (R2&#x2212;R1) on at least one film surface is 5&#xb0; or more, where the scattering angle is obtained from angles R1 and R2 (R1&#x3c;R2) at which the transmitted light intensity is Tmax(0)/100 relative to the maximum transmitted light intensity of halogen light incident perpendicularly to the film surface of Tmax(0).
